+### Customizing the comment
+
+By default, the `Comment` model will strip tags from the comment body. If you would like to modify this behavior, you can pass an callback to the `Comment::whenCreating` method. This callback will receive the comment model instance as a parameter.
+
+```php
+Comment::whenCreating(function (Comment $comment) {
+    $comment->comment = strip_tags($comment->comment);
+});
+```
